The Judicial Branch is a system made up federal courts and is headed by the U.S. Supreme Court. However, the Judiciary Act of 1789 split this system into the lower district and circuit courts. They also have the ability to strike down any law that is unconstitutional. Furthermore, there are three types of courts: District, Supreme, and the Court of Appeals. The District Courts are to keep cases over if they have authority. Courts if Appeals are here to give someone another trial if the first one was unfair. If it is equal to the first outcome they are guilty, but if the outcome is different, they will retire the case to the Lower Courts. The Supreme Courts are here to make a decision for the person who came out of the Court of Appeals if he lost.
